Thomas Caldwell

Oklahoma County sheriff’s investigators had been searching for Thomas Caldwell, 65, since Friday and tracked him to the mall parking lot.

Caldwell is accused of taking $40,000 from telephone terminals inside the Oklahoma County jail. Caldwell worked for Telmate, a telephone company that serves the jail, sheriff’s officials said.

He was seen removing cash from terminals at the jail and leaving via the building’s rear employee entrance, without depositing the money, officials said.

When deputies approached Caldwell on Tuesday, he pulled out a handgun and pointed it at his head, the department reported. Deputies spent five minutes talking to Caldwell before he dropped the gun and was taken into custody.
